Is it possible that a column is padded with spaces? I’d check the length of each column. Extra spaces to the right would make the columns unique. You can’t tell if the column is padded with blanks from your query. Checking the length would confirm each column is exactly the same.

Hello Scott,
I am wondering how the query matters here?
Also, I am just running a simple select from "TEST" with COL1, COL2, COL3 in the WHERE condition.
select * from 'TEST" WHERE COL1='3456' AND COL2='76542' AND COL3='5';
The actual Issue is I am unable to figure out why the table is having duplicate data in the primary key columns. Or how postgres accepted 2 rows with the same combination of the columns in the primary key constraint. I would expect it to throw primary key constraint violation error.
